Clay Arts Alert.
This is the idea... make a series of large fired vases based on stick bug egg cases. Just look at them!
This would be SUCH an amazing exhibition.
Every bug nerd on the planet will covet your vases.
Nature provides free ip!
(with my luck someone *will* do this & I'd never be able to afford one LMAO)

[Older pic] Here's a cockroach still just barely holding onto its ootheca/egg case! (Honestly I didn't know what an ootheca even was until after I had picked it up :P)

Spongy Moth - Lymantria dispar (pupal and egg casings) (formerly Gypsy Moth)
The last few posts featuring this insect showcased their egg cases being placed on urban structures such as wooden decks and metal fences. With such a big world to explore, Insects have to be resourceful with the materials around them. This is more so important given that the female Moths of this specie are flightless due to their weight, despite their large white wings, and thusly cannot travel very far to lay eggs from their pupal casing. Fortunately, the females have strong pheromones to catch the attention of the brown-colored males. The result: the many eggs cases you see along these sections of a tree! The natural environment provides ample hiding places for these egg masses, and given the amount of masses (and pupal casings) there were quite a few Moths calling this tree home. Unless the masses are scraped off and removed, the grey Caterpillars with colorful bumps will hatch next year and have themselves a pine feast to enjoy. Yes, pine needles are on the menu of these generalists, but if they can wriggle far enough from one tree to the next, they might find another new tree to feed on, leading to new infestations without proper management.
Though an invasive specie to North America and a potentially destructive pest as a result, the Gypsy Moth is still examined with curiosity and respect by scientists. As such, let me take you down a small rabbit hole I’ve been following the last few days. Due to the connotations that the word ‘gypsy’ has, a proposal was made to officially change the common name of this Moth. For the finer details, please refer to this article here from the Entomological Society of America, but the long story short is the former name was removed from the list of common names in July of 2021 and the new name was adopted and approved in early 2022. This new name aims to focus on the biology of Moth, and as such reflects the aforementioned egg cases like the ones on the trees here. The new name is Spongy Moth, which seems to originate from "spongieuse", the French name for the insect (of course, referring to the spongy egg masses). This blog will adopt this name as well (posts will be adjusted), and I do approve of the new name since it actually reflects something that the Moth is known for. However, I do see this change taking a while to enter the common lexicon and due to the negative reputation of this insect as a defoliator, I can see the former name being used as slang. As well, while the common name may be applicable in North America since L. dispar is the only one of its genus here, there may be overlap with the masses of other Moths in the Lymantria genus, but since L.dispar gets all the attention, it’s hard to tell. Looking through this literature however, there many varieties of egg masses among the tropical species. Have a look for yourself.

@dani-aka-that-one-namechanger submitted: Roach ootheca I found while looking for BBs & fish tank rocks in a neighbor's yard. I don't think any roaches hatched from it though idk.
If the ootheca is split open on the seam there at the bottom then it hatched already.
Here's a cool video of cockroach babies hatching! Probably don't watch if you're squeamish about a bunch of baby roaches slowly squeezing out of an egg case.
